While gutters 11 :may l yfran'ie 4, I prefer,f sameto.,be carriedV by settionsin the bottoms offth'e' gutters and are threaded in nuts 19,'w 'ch are rigidly se- `-screws 18, which.project,.through.perfora-` cured to said gutters, with the perforations in IOO Along the upper. edges of gutter .arenorrnally IOS be ,rigidly secured in y the nuts' registering with the perforations in stantly made good from some external source.

the gutters. With such a construction by having the set-'screws arranged on both sides of and in the center of the bottom of gutters 11 the same may be leveled both longitudinally and transversely. In the end of each flask near one of the upper corners is an opening 20 for the escape of the non-condensable gases liberated from the steam, and 21 is a pipe-flange secured to the end of said flask around opening 20. 22 is a pipe conducting the water of condensation from the flasks to the hot-well.

In the operation of my device the coolingwater is pumped from a suitable circulatingtank through the header 13, from which it escapes through the branch pipes to the gutters above the flasks. When these gutters are filled, the water runs over the curved sides and down onto the sides of the flasks in a thin sheet to the troughs 14. This sheet of Water is considerably warmer than the normal atmosphere and vaporizes into the air between the flasks, tending to saturate such air with the water-vapor at its own temperature. Such warmed saturated air being considerably lighter than the normal atmosphere,

draws a fresh supply of normal air upward into contact with the warm wet surface of the flasks. This atmospheric vaporizing action carries off the heat from the outer surface of the water-film as fast as the inner surface of the film can absorb it from the metal with which it is in contact, thus carrying off from dissipation into the atmosphere the heat evolved by the steam condensing inside of the flasks. The exhaust-steam entering the flask at the lower corner through the branch pipes is forced through the zigzag course formed by the interior baffle-plates, condensing as it travels by transmitting its latent heat through the sides of the` flask to the descending film of water and outlet 20 as little more than non-condensable gases that were entrained in it. These gases escape through said outlet, While the water of condensation descends to the bottom of the flask and escapes through the pipes 22 and is carried to the hot-well. The circulating water escaping from troughs 14 to the main f trough is returned tothe circulating-tank,

from whence it is again pumped to the gutters 11. The duty of the water-film is thus reduced to transmitting the heat, from the metal surface on one side to the passing current of air on its other side by the vaporization of its own substance, the current of .circulating water being reduced to that which will keep the entire surface of the flask entirely covered, the same Water being used over and over again indefinitely, so long as the amount vaporized into the air is conan upward current ensues, which reaches the and The foregoing holds good for all gases which,

like steam, condense below atmospheric pressure and carry an appreciable amount of non-condensable gases entrained. For gases usually condensed considerably above atmospheric pressure-such as carbon dioxid, ammonia, 6to-requiring a strong vessel to withstand their internal pressure and which do not carry non-condensable gases to any appreciable extent, the channel-iron forming the frame of the flask may be replaced by bar-steel and additional stay-bolts inserted to brace the sides against external collapse.

While I have specifically described my invention, I do not wish to be understood as limiting myself to the exact details of structure herein shown and described, inasmuch as the same may be varied without departing from the spirit of my invention.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a device of the class described, a flask for receiving the steam, a gutter above said flask adapted to deliver a sheet of water to the sides of said flask, and means for leveling said gutters.

2. In a device of the class described, a flask for receiving the steam, a gutter supported on said flask having perforations in its bottom, threaded nuts secured to the bottom of said gutter, with their openings registering with the perforations therein, and set-screws extending through said perforations and having a threaded connection with said nuts, substantially as set forth.

3. In a device of the class described, a flask for receiving the steam, comprising a channeled frame and sheet-metal sides, a `gutter supported within the channel at the top of the flask, means for leveling said gutter, and lcurved edges on said gutter extending over the sides of the flask and inwardly to contact with said sides, substantially as set forth.

4. In a device of the class described, a flask for receiving the steam, means for feeding water to the sides of said flask, a utter beneath said flask, and side plates Iiinged to said gutter, substantially as set forth.

5. A device of the class described comprising a series of flasks, means for feeding a cooling fluid to the sides of said flasks, gutters bcneath each of said flasks, and a main gutter beneath a portion of each of said flask-gutters, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
